After remaining sunny all day, fog returned in the state capital late Sunday disrupting traffic.
“Snowfall is continuing intermittently in the hill states and another round of moderate to very heavy snowfall in neighbouring Uttarakhand, Himachal Pradesh and Jammu and Kashmir is expected within the next few days,” the weather office said.
Many trains were running behind schedule due to poor visibility and fog in the Northern (NR) and North-Eastern Railways.
